Here are some things going on today in your world of tech:

Shares of MobileIron (MOBL), which makes software to manage mobile devices inside corporate networks, are up 67 cents, or 7.2%, at $10.04, and earlier surged 10%, after Deutsche Bank’s Karl Keirsteadtoday reiterated a Buy rating and a $14 price target on the stock, saying it could benefit as companies phase out the use of BlackBerry (BBRY) devices and software in favor of Apple’s (AAPL) iPhone.

Speaking of Apple, the stock is up 39 cents, or 0.4%, at $101.70, and earlier hit a new all-time high of $102.17, which equates to $715.19 before June’s seven-for-1 stock split.

There’s been various discussion this morning of the expected upcoming iPhone 6 debut.

Dan Niles of hedge fund AlphaOne Capital was on CNBC this morning with host Carl Quintanilla, talking about why he’s positive on the stock at the moment. Said Niles, who maintains Apple as his largest position, there “is a pretty consistent trading pattern of the stock outperforming the market by 10% to 20% in the two-month period leading up to product launches” and then tends to underperform.

But he thinks things “could be different this time,” with Apple continuing to rise because of a massive upgrade wave for the new iPhone.

In other Apple news, RBC Capital Markets’s Amit Daryananinotes Apple’s 10-Q quarterly filing shows a record $15.4 billion in off-balance-sheet items, suggesting ”AAPL is potentially not just gearing up for iPhone 6 ramp but could be securing capacity for a new product (iWatch?).”

And Cowen & Co.’s Timothy Arcuri thinks DRAM memory chip prices are set to lift on a squeeze in availability of all components because of so much capacity being shifted to the iPhone. That could benefit Samsung Electronics (005930KS) and Micron Technology (MU).

Micron stock is up 2 cent at $33.31.

And speaking of chips, Credit Suisse’s John Pitzer and colleagues observe the semiconductor supply chain has seen an-above-seasonal inventory build, in part affected by Apple’s impending product debut, but that it may not spell disaster for chip makers’ stocks.

Shares of Fairchild Semiconductor (FCS) are lower by 10 cents, or 0.6%, at $16.92, after the company this morning announced it will eliminate some chip-making facilities in West Jordan, Utah, and Penang, Malaysia, part of an ongoing program to lower costs and improve manufacturing, it said.

In response, chip analyst Craig Berger of the boutique firm Hedgeye wrote in a note to clients that the move, which is expected to save $50 million a year or more, should boost gross profit margin by 3 points and add 37 cents a share to annual earnings. He figures the stock has a fair value of $17.

RBC’s telecom anayst Jonathan Atkin today reiterates a Sector Perform rating on shares of Sprint (S), and cuts his price target to $7 from $8, writing that the company is facing lower average revenue per user after cutting prices to spur growth in postpaid wireless subscribers. Atkin’s main concern right now, however, is what kinds of cost cutting the company will do under newly appointed CEO Marcelo Claure.

Atkin meanwhile reiterates an Outperform rating on shares of Verizon Communications (VZ), and a $54 price target, calling it his favorite pick in the group, citing “subscriber growth, margin, and network leadership, as well as improving capital intensity.”

Verizon shares are up 39 cents, or 0.8%, at $49.03.

Shares of GrubHub (GRUB) are down $2.48, or almost 6%, at $40.28, after the company said it would sell 10 million shares, equivalent to almost 13% of the shares outstanding, in a follow-on public offering, diluting holders.
